FRANK o. PARKER, OE WASHINGTON, DIsTitICT OE COLUMBIA, ASSIGNOR or TWO-FIETIIS To FREDERICK C. SMITH, or WATERBURY, CONNECTICUT,

VACUUM MASSAGE DEVICE.

To all whom it may concern:

Be it known that I, FRANK O. PARKER, a citlzen of the United States ofAmerica, re-

siding at Awilfasliington city, District of- Columbia, have inventedcertain new and useful, Improvements in Vacuum Massage,

Vprovision of a device of this character'in which maximum vacuum can be,attained with a minimum water pressure, so that the vacuum can beapplied directly to the body and skin of a person, thus obviating vibraitory action upon the part treated for-massage purposes.

Another object of the invention is the provision of adevice in which thewater under pressure will intersect a vacuum chamber therebygenerating'- a high efficiency of vacuum' for creating maximum suctionin an applicator, whereby on applying the same to the body it willeffect a circulation in the tissues of the skin for the massaging of thesame without 'causing the bruising of the skin or otherwise injuring'it.

A further object of the invention is the provision of a massage deviceof this character in which a positive vacuum vfor producing suction inan application will be formed, without requiring excess or increasewater pressure in the device. s

A further object of the invention is the provision of a device of thischaracter which is simple in construction,'strong, durable, light inweight, reliable and efiicient in operatioil and inexpensive inmanufacture.

Other objects of the invention will be in' part obvious and in partpointed out here-H Specification of Letters Patent.

same. Fig. 3, is an end elevation. Fig. 4, 1s a transverse sectionalview near th( lower end of the device.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings by numerals. the device comprises a sphericalhollow body 5,. forming a vacuum chamber 6, and in diametricallyopposite points thereof are provided openings 7, one of which receivesthe inner end of a water outlet or discharge pipe 8, exttndingvertically down from the said body, the pipe being of any desired lengthand is fixed to the body in any preferred manner, so as to form a fluidtight joint therebetween. Fixed in the other opening 7, is t-he innerend of a water injector or )et nozzle 9, the same being in verticalvalinement with said outlet. or discharge pipe 8, and i's formed with acoupling nipple 10,

, to which is connected the inner contractedl end 11. of a shell 12,forming a bulb, which is preferably constructed from metal, 'the outerend being formed with screwthreads 13, struck therefrom for thedetachable engagementtliereon of a retaining ring 14,

adapted to removably secure in the outer p end of Said shell a centrallyperforated resilient disk 15,. preferably constructed from rubber. Thering 14 is formed with an ari-- nular inturned flange 16, adapted to lieagainst the outer face of the disk'l, to prevent the detachment of thesame when fastened in the shell. f

The central aperture or hole 17 in the disk '15, is designed to fitsn'ugly over the end of the faucet 18,`a depending lip or flange 19,being formed around said' aperture or hdle 17, within the bulb, wherebywhen water under pressure is admitted to saidbulb the pressure thereofwill operate to force the flange 19, into frictional contact orengagement with said faucet and to secure the same firmly' in positionthereon.

Leading from one side of thel body 5,-in communication therewith and atI right angles to the axis vof said pipe 8, is an air inlet nozzle 20,to which is connected a iexible tube 2l, the same being also connectedwith an applicator 22, which is of any ap `proved form and is detachablyconnected indentation thereon for.v allowing,r
